For 100 years, Thomastik-Infeld has been producing fine orchestral and fretted instrument strings in our Vienna factory. Every set we make has been precision-engineered and exhaustively tested until we were satisfied that they fulfilled our intentions - and live up to your musical expectations as well. Peter Infeld (PI)™ strings for violin employ cutting-edge technology to create an unparalleled playing experience for professional violinists.  They are ideal for solo work with orchestra, recitals and quartets, effortlessly projecting to the audience with depth and exquisite quality. They radiate a rich, dark tone with a beautiful timbre that can be both big and nuanced; they project easily to the back of any hall; response is immediate with extraordinary rich overtones; they are well-balance to meet the multi-faceted requirements of the violin in orchestral, quartet and solistic settings; they blend in with the subtlest tonal expression or stand out with a robust, sonorous sound. Violin set with Tin-plated E, 4/4 size.
